Twin-screw extrusion is known to be useful to do compounding. How about single screw extrusion? Can we use the same equation to calculate its specific mechnical energy (SME) value?
What kind of polymer are you working with? Pure polymers (without lots of additives) work well with single screw extrusion, but those with lots of fillers need twin-screw extrusion.
compounding usually needs a twin-screw extruder. in some embodiments, you can use a single screw but that includes knowing the proper compatibilizers for the compounding of polymers and Powder fillers. controlling the melt flow according to the material and the extruder working properties is another aspect that needs to be focused on. if you are forced to use a single screw for compounding check Compounding with Single-Screw Extruders from MARTIN GALE.
